A 65-year-old male was admitted to our hospital complaining of painful swelling of right sternocostoclavicular area. In the past history, he had no specific disease including trauma. After admission, chest CT and neck CT showed right empyema and right cervical abscess. Empyemectomy was performed through open thoracotomy and fistulous tract was detected on right parietal pleura and right sternocostoclavicular area. Osto-myelitis was also detected on right sternocostoclavicular area and removal of right cervical abscess, partial resection of proximal clavicle, resection of chondral portion of 1st rib, and partial resection of manubrium were performed. Empyema that extends from sternocostoclavicular osteomyelits, as in this case, is rare. Herein we report a case of loculated empyema with sternocostoclavicular osteomyelitis and neck abscess.
